Solution Overview

Problem

Existing vaporization devices face inefficiencies in heating and capturing fluid streams due to the need for oversized heaters with significant un-wetted surface areas, leading to incomplete vaporization and energy wastage, which can result in the discharge of liquid droplets.

Innovation Solution

A conductive heater element with a concave area, such as open-ended hexahedral, dimpled, or conical shapes, is used to capture and vaporize fluid efficiently, minimizing un-wetted surface area and optimizing heat distribution for rapid vaporization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the heater element is made larger to capture all fluid, then the fluid capture efficiency is improved, but the un-wetted surface area increases causing energy loss

Engineering Contradiction:
Improvefluid capture efficiencyVSAvoidenergy loss from un-wetted surface
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The heater element employs a concave surface geometry that curves inward to match the impinging fluid stream. This curved surface allows the heater to capture all fluid while the concave shape minimizes the exposed surface area to the environment, thereby reducing energy loss from radiation and convection on the heater's outer surfaces.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Use of energy by moving object

If the heater element is made smaller to reduce mass and energy consumption, then the energy required to heat the heater is reduced, but the fluid capture capability is insufficient

Engineering Contradiction:
Improveenergy to heat heater elementVSAvoidfluid capture capability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The concave geometry concentrates the heater's heating surface area into a compact volume that matches the fluid stream profile. This allows the heater to be smaller (reducing mass and energy requirements) while still capturing 100% of the fluid through the concave shape's ability to contain the impinging stream.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Productivity

If the heater element is made smaller to vaporize fluid rapidly, then the vaporization speed is improved, but the fluid capture area is insufficient

Engineering Contradiction:
Improvevaporization speedVSAvoidfluid capture area
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The concave surface geometry allows the heater to maintain a compact size for rapid heating while the curved shape extends the capture area to match the fluid stream. This enables fast vaporization rates without sacrificing fluid capture capability.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Ease of manufacture

If the heater element surface is made flat to simplify manufacturing, then the manufacturing complexity is reduced, but the fluid stream is not captured efficiently

Engineering Contradiction:
Improveheater element manufacturingVSAvoidfluid stream capture efficiency
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The concave geometry is achieved through simple forming processes such as bending or shaping the heater element material into a curved configuration. This curved shape efficiently captures the impinging fluid stream while remaining compatible with standard manufacturing techniques, balancing manufacturability with effective fluid capture.

Inventive Principle:
Principle #14Spheroidality (Curvature)
